I did love this type of thing in New Leaf because it still felt natural. It was initiated by the villager, only involved one furniture item at a time, and didn't happen too frequently (at least not for me). So everything about it still made the villager seem real. I could picture a friend asking me how to replace a certain item they didn't like anymore or gifting me something they owned but thought I would love more.
When people talk about wanting full control over their villagers' houses, I picture something more like HHD where you design their entire home and I just wouldn't want that. It takes me out of the game. I get that everyone plays Animal Crossing differently and some people do love the game solely for the design aspect, but that's not me so if anything like that were ever implemented I'd want it to be optional.
